WILLIAM GIBSON BELL, 0F NEWTON, AND WILLIAM HERBERT VINTO, OF BOSTON,MASSACHUSETTS; SAID VINTO ASSIGNOR TO SAID BELL.

TELEPHONE-CALL REGISTER,

To all whom t may concern Be it known thatwe, wWiLLL-xir GinsoN BELL andIVILLIAM HERBERT VINTO, citizens of the United States, and residents,respectively, of Newton, county of Middlesex, and of Boston, in thecounty of Suffolk, State of Massachusetts, have invented certain new anduseful Improvements in Telephone- Call Registers, of which the followingis a specification.

This rinvention relates to a mechanical device for registering telephonecalls, said device having means for independentlyT showing the number ofinward calls, the number of toll or long distance calls, and the numberof times when the line is reported busy.

The invention is an improvement on the apparatus disclosed by ourapplication for Letters Pat-ent of the United States iiled August 28,1912, Serial No. 717,519, said apparatus including a counter forregistering calls made, additional or secondary counters for registeringunanswered calls and the like, a lever operatively connected with thefirst mentioned counter and a support connected with said lever for atelephone element such as a receiver, or the portablereceiver-supporting standard forming a part of a desk telephone set, thesupport being normally held yieldingly in a raised position, and adaptedt-o be depressed bythe weight of a telephone element deposited thereon,the depression of the lever operating the accompanying counter.

The present invention has for its object first, to provide a simplifiedand improved construction of the parts of the apparatus which includethe lever, the telephone element support and the connection between thelever and the counter, whereby the uumber of parts is reduced to theminimum and accuracy of operation is increased, and secondly, to providemeans for automatically ringing a bell whenever the registeringapparatus is operated.

The invention consists in the improvements which we will now proceed todescribe and claim.

Of the accompanying drawings :#Figurel 1 represents a plan view of anapparatus embodying our invention, parts ot the casing cover beingbroken away. Fig. 2 represents a section on line 2 2 of Fig. 1.

Specification of Letters Patent.

Serial No. 770,025.

Fig. 3 represents a section on line 3 3 of Fig. 1. Fig. 11 represents aview similar to a portion of Fig. 8, showing the dog tripped to releasethe bell hammer. Fig. represents a section on line 5-5 of Fig. 1. Fig. 6represents a view similar to a portion of Fig. 5, showing the dog in itstripped pesition. Fig. 7 represents an end elevation or' the apparatus,showing a telephone transmitter associated therewith.

. The same reference characters indicate the same parts in all th'eiigures.

In the drawings :-12, represents a supporting structure for the parts ofour improved apparatus, the same being preferably a casing having acover 18.

14 represents a primary counter secured to the bottom of the casing.Said counter is of the type shown by the Veeder Patent, 634,073, andcomprises a rockshaft 15 adapted to operate a series of numbered disksor counter members, and lprovided with an oscillatory operating arm orlever member 16, the said rockshaft and arm being normally heldyieldinofly in predetermined positions and adapted to operate thecounter members by a movement from said positions, as fully described inthe said Veeder patent.

17 represents a lever fulcrumed at 18 to one end of the casing, andhaving a shorter arm connected by a pin and slot connection 19 with theoperating arm 16, and a longer arm projecting from the casing andprovided with an enlargement 2O adapted to support a telephone elementsuch as a receiver.

The arm 16 and the lever 17, connected as described, comprise a compoundlever through which the act of placing a telephone element upon theenlargement 20 causes the operation of the primary counter as presentlydescribed. The longer arm of the lever member 17 projects through anopening in the side of the casing and is normally held yieldingly in araised position by the operating arm 16, and is adapted to be depressedby the weight of a telephone element deposited on the enlargement 20.The depression of said longer arm moves the operating arm and rockshaftof the primary counter from their normal positions and operates thecounting members. Vhen lthe telephone element is removed, the rockshaftand operating arm of the primary counter return to their normalposition, by the action of a suitable spring as hereinafter described,and the longer arm of the lever 17 is raised, the apparatus being thusset for the next operation.

The primary counter registers all uses of the telephone and isautomatically operated bythe usual manipula-tions of the telephone intaking the portable telephone element from and restoring it to itsplace.

The apparatus oit our invention includes a series of alined secondarycounters 141; each of the same type as the primary counter, theoperating arm 16a of each secondary counter being `termed to projectthrough a slot in the cover 18, and manually movable independently fromits normal position. The secondary counters may be used to manuallyregister calls and uses not chargeable to the subscriber such as inwardcalls, toll calls, and line busy uses.

A secondary counter may be provided to normally register outward calls,it desired. The cover 13 is provided with sight apertures 23,registering with the different counters, 14 and 14;, and may haveinscriptions adjacent to the sight openings such as Total calls, Inwardcalls, Outward calls, and Line busy.

The improved apparatus above described is of compact and simpleconstruction, the lever 17 and the telephone element support beingformed as one part and constituting the only considerable protuberancefrom the casing. Said lever is directly connected with the operating armof the primary counter so that there is no liability ot failure toautomatically actuate the primary counter in consequence of lost motionin the connections between the telephone element support and theoperating arm and roekshaft of the primary counter.

Our invention includes an alarm or audible signal adapted to be operatedby the operation of either of the described counters. As here shown, thealarm includes a bell or gong 24 attached to the cover 13, and twospring-projected hammers 25 and 25a, each adapted to strike the gong,the hammer 25 being projected against the gong by a spring 26, and thehammer 25a by a spring 26H. Mechanism is provided for successivelyretracting and releasing each hammer, the hammer 25 being retracted andreleased by a movement of the operating arm 16 of the primary counterfrom its normalposition, while the hammer 25a is retracted and releasedby a movement of the operating arm 16a kof either secondary counter fromits normal position.

27 represents a dog adapted to engage the pivoted arm 28 forming a partof the shank of the hammer 25. One end of said dog is pivoted te one armof a bell crank lever E29 which pivoted at 30 to the bottom ot thecasing. The other arm ciq the lever Q9 contacts with a lever arm 31,Fig. 2, formed on the operating arm l@ ot the primary counter, and isheld against said arm 31 by a spring 32 attached to the dog 27. The saiddog is reciprocated by the lever arm and spring 3Q, the lever arm movingthe dog in the direction indicated by the arrow fc when the operatingarm 1G is moved from its normal position by the lever li' and causingthe dog to retract the hannner The spring nieves the dog in the oppositedirection when the lever 17 and operating arm 1G 'are released by theremoval of the telephone element. The dog 27 is tripped during itsmovement by the lever arm 31, by means ot a fixed block 34 on the bottomoli the casing, and an incline 35 on the dog, said incline moving ontothe block so that the dog is raised as indicated by Fig. et, andreleases the hammer which thereupon strikes the gong.

Q7 represents a dog adapted to enga the pivoted arm 2S forming a partoit the shank of the hammer Q5, Said dog is pivoted `to a lever 29awhich is pivoted at 3G to the casing. To the swinging` end ot the lever29a is attached one end ot a l ar the other end of which is attached toa lever 29h, 1, also pivoted to the casing, the bar 38 being supportedby said levers which permit the bar to swing edgewise. ',lhe bar oxtendsacross and is in sliding contact with each of the counter-operatinglevers 1W. A '1 spring 39 normally holds the bar 3S against all theoperating levers 16a. fr movement oi either lever 16a from the positionshown by Fig. 5 to that shown by Fig. 6, displaces the bar 38 laterallvfrom its normal iosition and causes said bar to move the dog 27 in thedirection ol the arrow y, said dog being thus caused to retract thehammer 25W This movement of the dog causes its inclined bottom edge toride on a lixed block Si, the dog being thus raised or tripped as shownby Fig. 6, and caused to release the hammer which now strikes the gong.lVhen the displaced operating` lever 162L is released, the spring 39restores the bar 38, levers 29 and 29", and dog 27a to the positionshown by Fig, 5, the dog again engaging the hammer shank. It will now beseen that the dog 27 is reciprocated when the primary counter 14 isoperated, and is caused to successively retract and release the hammer25, and that the dog 27 is reciprocated when either of the secondarycounters 111Z1 is operated, and is caused to successively retract andrelease the hammer 25, so that the operation o any counter causes anaudible signal. It is obvious that two gongs may be provided if desired.

is hereinbetore described, the rockshat and the arm or lever member 16of the primary counter are yieldingly held in predetermined positions,and the lever member 17 has its longer arm which is provided with theenlargement 20 normally held yieldingly in raised position by the arm16. And as also explained, the secondary counters 14a are of the sametype as the primary counter. The springs Which so yieldingly hold therockshaft-s are indicated at 15a by dotted lines in Fig. 1.

The lever enlargement 20 is preferably formed to extend entirely acrossthe diaphragm-containing end of a telephone receiver 41 depositedthereon, as indicated by Fig. 7, and to exclude dust and insects fromthe diaphragm when the transmitter rests on said lever enlargement. Thecounter casing 12 may be supported in any suitable Way, with the leverenlargement in position to be depressed by the receiver When the latteris replaced on the usual supporting hook. The lever enlargementtherefore constitutes a diaphragm shield or protector when the receiveris not in use.

7e claim l. A telephone call register comprising a casing having a sightaperture in its top, a counter mounted in said casing and coincidingwith said sight aperture, a compound lever composed of an innercounter-actuating member located Within the casing, and an outer levermember fulcrumed to one Wall of the casing and jointed at its inner endto the inner member, the said outer member having a longer armprojecting through one side of the casing and adapted to support atelephone element, a bell crank lever mounted on the base of the casingand engaging said coin-actuating member, and a spring act ing onv saidbell crank lever to hold the longer arm of said outer member in anormally raised position.
